Description
Technical field
The present invention relates to a kind of vehicle light screen, be used for from the driver's seat of vehicle or the place ahead of front-seat passenger-seat or side and the Der Scheinwerfer mit FernlichtAbblendlichtStandlicht light of advancing along relative direction that comes and sunlight etc. block.
Background technology
The conventional vehicle light screen of this class is constructed to make and in for example forming the anti-dazzle device body of hollow shape retainer is set, and will be inserted in the retainer rotationally in the inserting side part on the side that is become L shaped axle by general curved, and will partly be mounted to the vehicle body side at the installation side on the opposite side of described axle via carriage, so that described axle is rotatably supported on the carriage, and the anti-dazzle device body is rotatably supported on the axle.
Under the situation that the light that light shone of the Der Scheinwerfer mit FernlichtAbblendlichtStandlicht of advancing such as sunlight and relative direction comes from the place ahead of driver's seat or front-seat passenger-seat, the anti-dazzle device body is turned down via axle, so that, come Der Scheinwerfer mit FernlichtAbblendlichtStandlicht light and sunlight to block along relative direction in the face of driver's seat or front-seat passenger-seat.
Also have, under the situation of coming from driver's seat or front-seat passenger-seat side such as sunlight and the light that Der Scheinwerfer mit FernlichtAbblendlichtStandlicht light shone of advancing along relative direction, the anti-dazzle device body is turned down via axle and is arrived the vehicle side with respect to carriage turns again, the anti-dazzle device body is positioned at the vehicle side thus, penetrates next irradiates light (referring to Japanese unexamined patent No.9-254649) to block from the vehicle side quadrature.
For above-mentioned vehicle light screen, light is roughly fixed by the scope that the anti-dazzle device body blocks.But, in recent years, consider that the anti-dazzle device of sliding type occurred, this anti-dazzle device is considered from the vehicle side and the sunlight that comes is constructed along the situation that the fore-and-aft direction of vehicle moves from being raised to the situation of sunset long-duration driving vehicle day.
Specifically, the sliding type anti-dazzle device occurs, and it is constructed so that the anti-dazzle device body can slide with respect to axle, so that can be changed (referring to Japanese unexamined patent No.2004-9883) in the light shield portions of vehicle side.
For this class sliding type anti-dazzle device, shown in Figure 10 (front elevation of conventional sliding type anti-dazzle device) and Figure 11 (along the section drawing of the B-B line intercepting of Figure 10), as the conventional anti-dazzle device that the shading scope is fixed, the anti-dazzle device body is rotatably supported on the b, this b is bearing on the carriage c with inserting, and this carriage c is mounted to the ceiling part (not shown) of carbody plate.
Axle b is rotatably supported on the bearing assembly d that is installed among the anti-dazzle device body a.For example, in order from leaving the lip-deep state of ceiling in the anti-dazzle device body to be turned to use location on the windscreen side in driver's seat or front-seat passenger-seat the place ahead, anti-dazzle device body a rotates around axle b.
Also have, for the shading orientation is changed to the vehicle side, promptly change to the side window side from the windscreen side, anti-dazzle device body a rotates around carriage c around axle b rotation and axle b itself, and anti-dazzle device body a rotates along the left and right directions of vehicle thus.
And the sliding type anti-dazzle device shown in Figure 10 and 11 has bearing assembly d, so that can freely change the shading scope by the axial direction slip anti-dazzle device body a along axle b.
That is to say that bearing assembly d comprises support body e that is formed by resin molded body and the leaf spring f that is installed on this support body e.Axle b is inserted among the axis hole m among the support body e, by this axis hole axle b by rotatably mounted.
And then a part and the leaf spring f Elastic Contact of the outer surface of axle b can obtain the torque when axle b rotates at anti-dazzle device body a thus.
In more detail, anti-dazzle device body a has anti-dazzle device body a-1 and the a-2 that conchoidal separates.Anti-dazzle device body a-1 separately and a-2 combine togather in their crooked outer surface mode outwardly, form the resin core material a-3 of hollow thus.
Also have, by covering the outside face of constructing resin core material a-3 with anti-dazzle device crust a-4, this crust a-4 is formed by fabric (woven fabric), adhesive-bonded fabric (nonwoven fabric), synthetic resin board etc.
The anti-dazzle device body a-1 that separates and the a-2 that constitute resin core material a-3 assemble by engaging between the locking part h on being arranged on a lock pawl g on the anti-dazzle device body a-1 that separates and being arranged on another anti-dazzle device body a-2 that separates.
